Fig. 3: ARPES images of TBG near the magic-angle.
From: Observation of a flat band and bandgap in millimeter-scale twisted bilayer graphene
a Optical micrograph with highlighted contrast of the TBG sample. Horizontal striations are scratches of the substrate rear. b ARPES image at the K points of TBG. c, d Energy dispersion curve along the kx = 0.016 [Å−1] line in b, f. e ARPES image together with the overlaid schematic TBG band structure with θc = 1.1°. Band structures without the interlayer interaction are shown. Blue and red bands correspond to the lower and upper graphene layers. f Single-particle spectral function of TBG with θc = 1.08°, calculated by the effective continuum model.
